As bereft of shame as of any other emotion, Arinix stripped off his clothing and pulled on one of the coverall-type outfits. Mark did the same. It was soft but thick and sealed up high on the neck with what appeared to be a magnetic closure. There were heavy boots in an assortment of sizes, and he soon found a pair that fitted. While he did this, Arinix was making a call on a very ordinary-looking phone that was prominently stamped "Western Electric"-they would be surprised if they knew where their apparatus was being used- speaking a language rich in guttural sounds. They left the room by a different exit, into a wide corridor, where transportation was waiting for them. It was a vehicle the size of a large truck, a teardrop shape riding on six large, heavily tired wheels. It was made of metal the same color as their clothing, and appeared to have no windows. However, when they went inside, Mark saw that the solid nose was either transparent or composed of a large viewsereen of some kind. A single driver's seat faced the controls, and a curved, padded bench was fixed to the other three walls. They sat down, Arinix at the controls, and the machine started. There was no vibration or sound of any exhaust; it just surged forward silently at his touch.

"Electric power?" Mark asked.

"I have no idea. The cars run when needed."

Mark admired his singleness of purpose but did not envy him. There was only one thing in the man's life-to run from the solar fire and save what possibly could be saved from the flame. Were all of his'people like this?

Strong headlights glared on as they left the corridor and entered what appeared to be a tunnel mouth. The walls were rough and unfinished; only the roadway beneath was smooth, dropping away at a steep angle,

"Where are we going?" Mark asked.

"Under the river, so we can drive on the surface. The island above us-what is the name Einstein-?"

"Manhattan."

"Yes, Manhattan. It is covered by the sea now, which rises almost to the top of the cliffs across the river from it The polar caps melted many years ago here. Life is very harsh, you will see."

The tunnel ahead curved to the right and began to rise sharply. Arinix slowed the vehicle and stopped when a brilliant disk of light became visible ahead. He worked a control, and the scene darkened as though a filter had been slipped into place. Then, with the headlights switched off, he moved forward until the light could be seen as the glaring tunnel mouth, growing larger and brighter, until they were through it and back on the surface once more.

Mark could not look at the sun, or even in its direction, despite the protective filter. It burned like the open mouth of a celestial furnace, spewing out light and heat and radiation onto the world below. Here the plants grew, the only living creatures that could bear the torrent of fire from the sky, that welcomed it. Green on all sides, a jungle of growing, thriving, rising, reaching plants and trees, burgeoning under the caress of the exploding star. The road was the only visible manmade artifact, cutting a wide, straight slash through the wilderness of plant life, straining life that leaned over, grew to its very edge, and sent tendrils and runners across its barren surface. Arinix threw more switches, then rose from the driver's seat.

"It is on automatic control now. We may rest."

He grabbed for support as the car slowed suddenly; ahead, a great tree had crashed across the road, almost blocking it completely. There was a rattle of machinery from the front of the car, and a glow sprang out that rivaled the glare of the sun above. Then they moved again, slowly, and greasy smoke billowed up and was blown away.

'The machine will follow the road and clear it when it must," Arinix said. "A device, a heat generator of some sort, will burn away obstructions. I am told it is a variant of the machine that melted the soil and rock to form this road, a principle discovered while observing the repulsive sun that has caused this all, making heat in the same manner the sun makes heat. We will turn its own strengths back upon it."
